Are you kidding?
I hope I never outgrow video games. My love of video games is something I'll pass along to my kids (but don't worry, they will still get outside time running around).
I just turned 28 last week. I just got a Wii to add to the system (Xbox360 and PS2) a few weeks ago. I'm hoping to get a PS3 for Christmas to round out the selection.
Recently, I've been known to waste an entire weekend (25+ hours) playing COD4, Halo3, Oblivion, Forza2 Zelda:TP, FFXII, or anything else I can get my hands on.
Up next, Metroid Prime 3, Assassins Creed, who knows what else.
